October 10, 1995 Mr. A. C. Ray Department of Environmental Quality VIRGINIA POWER Piedmont Regional _water Office P. 0. Box 6030 Glen Allen, Virginia 23058 RE: SURRY POWER STATION OIL DISCHARGE CONTINGENCY PLAN (ODCP)

Dear Mr. Ray:

In your July 25, 1995, letter to Mr. Dennis Flippen of my staff, you summarized some concerns about the leak detection systems in place at some of Virginia Power's facilities in your jurisdiction.

Included in your letter, as well as our responses, are references to the July 13, 1995, DEQ-Virginia Power meeting to initially discuss your concerns. Virginia Power's responses and corrective action proposals were provided in a August 25, 1995, submittal for each facility except Surry Power Station. It was agreed that the response for Surry would be submitted by October 13, 1995. The response for Surry is provided below.

Surry Power Station:

• DEQ Concern: "The long stretch of underground piping at the Surry Power Station which runs from the truck transfer point to the AST [Aboveground Storage Tank] did not appear to have adequate leak detection coverage. Also the short length of underground piping associated with the waste oil AST appeared to lack leak detection coverage. Virginia Power indicated they would study various options to address leak detection coverage for the underground oil transfer piping at the facility."

• Response: We have determined that the facility no longer uses the short length of u~derground piping associated with the waste oil tank. Waste oil is now transferred through a hose into a tank truck. Therefore, no leak detection will be necessary for the short length of waste oil piping.

The long stretch of underground piping which runs from the truck transfer point to the AST is only used once or twice annually. Considering the difficulty of installing vapor or groundwater monitoring wells in the vicinity of the piping, and the infrequent use of the piping, we feel that installation of a leak detection system would be impractical.

Therefore, we propose to annually pressure test the underground pipeline which runs from the truck unloading station to the AST.
